Pale Dawn

The “Pale Dawn” tileset has a calm, restrained style
designed to work well with lots of data points. It’s less about
the geographical information as such, and more about providing a
suitable background to foreground information.

This map is constructed using a single image layer of CloudMade
tiles. The tiles are in spherical mercator coordinates, and the map has
standard interaction controls, so this basic example is a useful
starting point for customization. Register
